Abstract :
A tape conductor and a multistrand wire, each of which has two different types, have been fabricated in long lengths. Nb3 Sn filaments of one type of the tape conductor are twisted. A pancake magnet (46 mm inner and 80 mm outer winding diameter) has been made of those tape conductors and tested in backup field of 7.5 Tesla. The tests have revealed that the twist improves stability of the tape conductor. Total magnetic field of 9.8 T was achieved using the tape with twisted Nb3 Sn filaments for windings of end pancake modules. Both types of the tape were made by external tin diffusion method and have critical current capacities of 240 Amp at 10 Tesla. The multistrand wires were manufactured by tin cored internal diffusion method. One type containes single tin core, the other type seven tin cores. The single and seven tin-cored wires have been successfully drawn to diameters of 0.62 and 1.26 mm respectively. Critical current densites of those wires were found to be
